I find it difficult to invest time in reading this when the author demonstrates such a basic misunderstanding of copyright:
>...software, by default, probably cannot be used, modified, or redistributed without a license from the copyright holder.
Of course it can be used and modified. It's the redistribution that is covered by copyright law.
>...you can’t really use software without someone giving you permission.
This is completely false, except where a license is required to obtain a copy to begin with. It is the license that creates the restriction, not the copyright.
